IMPROVEMENT IN CLOTH-MEASURING MACHINES.

Specication forming part of Letters Patent N0- 152Q234, dated June 23, 1874; flpPliCaOIl ld April 14, 1874.

To all whom it may concern:

Be it known that I, WILLrAiu M. KEYES,

4of Stanstead, in the county ot' Stanstead,

Province of Quebec, Dominion of Canada, have invented a certain new and useful Improvement in Mechanisms for Measuring Cloth, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which my invention appertains to make and use the same, reference being had to the accompanying drawing forming a part of this specification, in which Figure l is an isometrical perspective view of my improved cloth-measuring machine. Fig. 2, is a sectional view, showing the indicator. l Y l Like letters referto like pai-ts in the different gures of the drawing.

My invention relates more especially to that class of measuring-machines which are used for measuring cloth from the cut; and consists of a novel construction and arrangement of the parts, as hereinafter more fully set iorth and claimed, by which a cheaper and more eii'ective device of this character is produced than is now in common use.

The extreme simplicity of my invention renders an elaborate description unnecessary.

In Figure l, A is the frame or base of the machine, and B B uprights, connected by the cross-bar J, and carrying the main roller H. A gravita-ting Jfriction-roller, K, is disposed `in the arms L L, which are pivoted to the uprights B B at M. A stud, S, projecting from the upright B acts in conjunction with the projection T on the arm L to prevent the roller K from being thrown back too far. The side pieces of the frame A are provided with grooved runlets or ways a', in which the traversing standards or uprights C G C C' are arranged. The lower ends of these standards are iitted with nuts, in which right and left hand screws on the crankshafts y y work in such a manner that when the shafts are turned in onegdirection the standards will be caused to approach each other, and when turned in the opposite direction, to separate. rlhe standards C C are provided with chucks D D', fitted to revolve in sockets, and the standards C C with chucks, having the cranks E F. The journal R 1 f the main roller His provided with a crank-pin, P, Fig. 2, which works in the slot Q of the index-lever N. This lever is pivoted in a vertical position to the upright B, and is provided with a pointer or indexnger, e. An indexwheel, W, having ratchet-teeth on its periphery, is arranged to revolve freely on a stud or pin projecting from the standard B, and is actuated by the long pawl e and short pawl d, which are hinged tothe lever N, but respectively above and below its center of motion.

From the foregoing the nature and operation of my invention will be readily understood by all conversant with such matters.

The roll or cut oi' cloth to be measured is wound on the board represented by the dotted lines M, and held by the chucks G D, which are caused to grasp the board by turning the crank y. Theweb of cloth represented by the dotted lines b b is then passed over the roller H, under the friction-roller K, under the tension-roller J, and around the board a., held in the chucks G D. If, now, the crank F is turned, the roller H will be revolved, causing the lever N to vibrate and theindex-wheel WV to revolve in a manner which will be readily obvious. The index-wheel should be spaced and numbered properly with yards and fractional parts of yards. The quantity of cloth necessary to start up the machine. or to reach from the roller H to the board a may be measured and accounted for in any usual manner, or by causing the wheel H to Aturn as the end of the cloth is passed over it from M to a the index will register the quantity. It will be seen that the cloth may be run in either direction through the machine, and that after being measured by ruiming it through in one direction the measurement may be verified by'reversing the movement and running it through in the opposite direction. In case sutiicient tension is; not obtained by the roller J ,i the ards C C provided with the chucks D G, and cloth may be carried under another tensionmounted on the screw crank-shaft Y, subroller (not shown) on the opposite side of the stantially as and for the purpose specified.
